TECHFILL BREATH THERMO COAT
By MIZUNO for MARGARET HOWELL
Mizuno and Margaret Howell add a padded winter coat to their shared line this week. The TECHFILL BREATH THERMO COAT goes on sale on 28 October, built around an insulation material that Mizuno developed in-house.
The project, called MIZUNO FOR MARGARET HOWELL, is a long-running one. The partnership between the Osaka-born sportswear maker, founded in 1906, and the London label known for plain, durable clothing began in 2017 with a running shoe. It has since grown into seasonal outerwear and footwear, which makes this coat a continuation of an established range rather than a one-off.
The shell is a lightweight nylon ripstop with a dry hand. A taslan finish gives the surface a natural, slightly matte look and keeps the weight down. The filling is TECHFILL BREATH THERMO, Mizuno's own fibre, which the brand says absorbs moisture to generate heat while retaining warmth.
The cut is a relaxed, mid-length coat. Drawcords at the hem let the wearer adjust the silhouette, while a stand collar that fastens up to the chin and a drawcord hood limit wind getting in. Hand-warmer pockets are lined with a brushed fabric, and a reflective tape across the back is the only sporty signal on an otherwise restrained garment.
The TECHFILL BREATH THERMO COAT is priced at 79,200 yen including tax. It is sold at selected Margaret Howell stores and on its online store in Japan, and on Mizuno's online store.
